Specification of Letters Patent.

Patented Nov. 2, 1909.

Application filed June 5, 1909. Serial No. 500,274.

To all whom it may concern:

Be it known that I, JOSEPH GAYNOR, a citizen of the United States,residing at New York city, Brooklyn, county of Kings, State of New York,have invented new and useful Improvements in Display Apparatus, of whichthe following is a specification.

This invention relates to an apparatus for displaying in an endlessseries a number of cards bearing advertisements, pictures or similarmatter. The construction is such that single cards are successivelypicked up and rotated in a cycle in such a way that the cards arerighted while exposed to view and stacked up when out of view. In thisway compactness is insured while the cards may be readily withdrawn andreplaced by others bearing different display matter.

In the accompanying drawings: Figure 1 is a front view of my improveddisplay apparatus; Fig. 2 a similar view on an enlarged scale, with thefront plate omitted; Fig. 3 a cross section on line 33, Fig. 2; Fig. 4 adetail of the lower part of the track; Fig. 5 a rear view of the drivingmechanism; Fig. 6 a plan of part thereof; Fig. 7 a top view of the facewheel; Fig. 8 a side view of a modification of the driving mechanism;Fig. 9 a plan thereof, and Fig. 10 a cross section through amodification of the guide rail.

Within a casing 10, having a window 11, is fitted an endless trackcomposed of a pair of parallel slotted guide rails A. Each of theserails comprises a vertical front section 12, a rearwardly inclined topsectionor upper gravity run 13, a vertical rear section 1-1, and aforwardly inclined bottom section or lower gravity run 15. Upperinclined section 13 is provided with a charging orifice 16, while ahorizontal step 17 is formed at the junction of rear section 14 withlower run 15.

Rails A, constitute guides for the cards 18 hearing the advertisements,pictures or other matter to be displayed. Each card is mounted in aseparate frame 19 having gudgeons 20 which may be brought intoengagement with the rails through charge orifices 16. Means are providedfor carrying the frames in a continuous cycle along the track by pushingthe bottom frame from step 17 into lower gravity run 15, lifting italong front rail-section 12, and depositing it through upper gravity run13 upon the top of the stack of frames superposed on steps 17 The meansfor pushing the bottom frame off step 17 and into lower run 15, are asfollows: Upon a power shaft 21, journaled in standards 22 are fitted apair of face wheels 23, each having a single tooth 2 1 adapted to impartintermittent rotary movement to a notched disk 25 turning on a verticalaxis 26. Notches 27 of this disk are adapted to successively engage thegudgeons 20 of the bottom frame 19 and push the same off step 17 intorun 15, where the frame descends by gravity. \Vithin run 15, gudgeons 20are grasped by lifters 28 projecting from a pair of endless feed chains29. The lifters are so spaced as to correspond to the height of frames19 and are preferably arranged in pairs, so as to straddle the gudgeons,as shown. Feed chains 29 engage upper sprocket wheels 30 and lowersprocket wheels 31 which are journaled in standards 32 and are solocated that the forward runs of the chains flank the frontrail-sections 12. Mot-ion is imparted to lower sprocket wheels 31 fromshaft 21 by a suitable transmission, such as chain wheels 33, 84: andchains 35. A shield 36 extending directly back of the front chain runserves to right frames 19 during their upward travel.

It will be seen that when a frame has been pushed into gravity run 15,its gudgeons 20 will become engaged by lifters 28 which will carry theframe beneath wheels 31 along front rail-sections 12 and over wheels 30,to be thence released from lifters 28 and descend along upper gravityrun 13. Thus the frame is deposited upon the top of the stack supportedon steps 17. While the frames ascend successively in the mannerdescribed along the front of the apparatus, they will, by shield 36, beturned into an upright position, so that the matter disdisplayed thereonis fully exposed to View through window 11. During its travel each framewill be reversed from the time it is withdrawn from the bottom of thestack until it is deposited upon the top thereof, as it is compelled tomake a turn through 180. In this way, opposite views of each card willbe exposed to view upon alternate tri ps, so that the quantity ofdisplay matter may be duplicated without necessitating a correspondingincrease in the size of the apparat-us.

Figs. 8 and 9, illustrate a modification of the mechanism for pushingthe frames off steps 17 and into gravity run 15. Here there is mountedin standards 32, a power shaft 37, carrying lower sprocket wheels 31,and in addition thereto a pair of eccentrics 88. The straps 39 of thelatter are provided with integral arms 40, notched as at 41 for engagingthe gudgeons 20 of the bottom frame 19. It will be seen that eccentrics38 will impart reciprocative movement to arms 40, so that the latterwill draw successive frames into the gravity run.

In Fig. 10, the guide rail is made in the form of a tube 42 slitted asat 43 for the admission of gudgeons 20. The chain 29 is located withintube 42, so that its lifters will grasp the gudgeons in the manneralready described.

I claim:

1. A display apparatus comprising an endless track having connectedfront and rear sections, reversible frames having gudgeons engaging thetrack and adapted to be stacked along the rear traclcsection, an endlessfeed chain having lifters adapted to engage the gudgeons, and a shieldback of the front run of said chain and adapted to be engaged by theframes.

2. A display apparatus comprising an endless track composed of a frontupright section, an upper inclined section, a rear upright section, astep at the bottom thereof, and a lower inclined section, frames havinggudgeons engaging the track and adapted to be supported by the step,means for forcing the gudgeons from the step into the lower inclinedtrack-section, a feed chain having lifters adapted to engage the gudgeons, and a shield back of the front run of said chain and adapted tobe engaged by the frames.

3. A display apparatus comprising an endless track having front and rearsections connected by an upper gravity run and a lower gravity run,reversible frames having gudgeons engaging the track and adapted to bestacked along the rear track-section, means" for conveying the framesfrom the rear track-section to the lower gravity run, means for rightingthe frames, and means for propelling the righted frames along the fronttrack-section and conveying them to the upper gravity run.

Signed by me at New York city, (Manhattan,) N. Y., this 4th day of June,1909.
